There's a parallel issue with traditional meat farmers banding together to prevent labelling this as "meat". I agree with them when it comes to plant based meat imitators but cultured meat is a harder sell for me. This is actual meat tissue.
Effective subsidies, like when margarine legally wasn't allowed to be sold yellow:

Force the vat-meat makers to call their product something unappetizing, and save the cattle yards.
With time, it'll be an increasingly losing battle for the farmers.
That said, there is little consistency in how things are named and often it comes down to the relative power of one special interest over another. We shall see how this shakes out.
